STEAM-BOILER FOR TRACTION-ENGINES.

SPECIFICATION forming part of Letters Patent No. 284,134, dated August'28, 1883.

- Application filed January 21, 1883. (No model.)

To all whom it" may concern:

Be it known that I, LA FAYETTE LILLARD, a citizen of the United States, residing at Dixon, in thecounty of Solano and State of California, have invented a new and useful Boiler for Steam Traction-Engines, of which the following is a specification.

My invention relates to improvements in traction engine boilers in which a safetydamper is used to control the heating of fines; and the objects of my improvements are, first,to prevent the collapsing of theflues either when the traction -'engine is running on a sideling place or when it is swamped,with some of the fines out of water; second, to afford facilities for utilizing the greatest amount of heat. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure lis a vertical and longitudinal sect ion of boiler. Fig. 2 is avertical cross-section of boiler.

Similar letters refer to similar parts throughout the two views.

F is fire-box at middle of boiler B. Sis

smoke-box, separated from fire-box by the pardamper D, attached to a reciprocating bar, t,

which slides in the flues h h. This safetydamper can be made to close either return-flue, thus preventing the flnes of either end of the boiler from overheating. If the furnace F S Fig. 1 that the furnace is at right angles with the boiler, and in order to get sufficient length of fire-box and a large heating-surface the fun nace extends below theboiler and projects from it on either side. In all other respects the boiler should be made like ordinary locomotive-boilers; The said furnace being at the middle of the boiler, it is very easily. completely surrounded with water, and it is out of the way of the driving-wheels. The extra weight being at the middle of the boiler, it will balance well on its bearings.

i As shown in Fig. 2, the top of furnace within the boiler should be curved in order to give extra strength andto insurethe furnaces being always covered with water. I

WVhatI claim as my invention, and desire to secure by Letters Patent, is-

The combination, in atractionengine boiler, of adouble set of retnrnflnes, hh,witl1 asafetydamper, D, attached to a bar which reciprocates within the smoke-boxS and between the return-fines h h, substantially as shown, for the purpose specified.
